Geometrical and electrical properties of NTC polycrystalline thermistors vs. Changes of sintering parameters
(Belgrade : International Institute for the Science of Sintering, 2006)
NTC thermistor powder was made of a Mn, Ni, Fe and Co oxide mixture calcinated at 1050°C / 60 min. The powder was milled in a ball mill down to an average particle diameter of 0.9 μm. Small disc shaped pills of the powder ...
Influence of Bi2O3 on microstructure and electrical properties of ZnO-SnO2 ceramics
(Belgrade : International Institute for the Science of Sintering, 2007)
The effects of small amounts (0.5; 1.0 and 1.5 mol. %) of bismuth oxide on the microstructure and electrical properties of ZnO-SnO2 ceramics have been studied. Starting powders of ZnO and SnO2 were mixed in the molar ratio ...
